Question

How fast does water flow from a hole at the bottom of a very wide, 5.8-m-deep storage tank filled with water? ignore viscosity?

Answer 1

To calculate the speed of the water leaving we use the formula,

$v=\sqrt{2gh}$

Here h is the height of the water above the hole and g is the acceleration due to gravity.

Given, $h=5.8 m$

Substituting the given value in above formula we get

$v=\sqrt{2\times9.8 m/s^{2}\times5.8m }$

$v=\sqrt{113.68}$

$v=10.7m/s$

Thus, water flow from a hole at the speed is 10.7 m/s
